The makers of the film "London Has Fallen" tried to expose the personal details of alleged pirates on a Comcast connection. Instead of filing a regular lawsuit, the company opted for a DMCA subpoena shortcut. This effort failed, with the court noting that it has long been established that these subpoenas are not available in file-sharing cases.

In the early 2000s, the RIAA filed lawsuits against tens of thousands of alleged music pirates.

The music industry had just defeated Napster, but P2P file-sharing remained a massive problem.

Millions of people flocked to alternatives such as KaZaA, Morpheus, Grokster, and eDonkey. Since regular education campaigns failed to curb this trend, the lawsuits were supported to alert the public that piracy is not without consequences.

Filing full-blown lawsuits can be an expensive exercise so the RIAA attempted to take a shortcut by applying for so-called DMCA subpoenas. Unlike regular subpoenas, these are not reviewed by a judge and only require a signature from the court clerk.

Internet providers were not happy with this trend and objected. They argued that DMCA subpoenas are only valid when an Internet service stores or links to the infringing content (such as YouTube, Twitter and Facebook), not when they merely pass on traffic.

Various courts have agreed with ISPs since and effectively banned the practice more than 15 years ago. If copyright holders want to go after alleged pirates, they have to file a complaint and request a regular subpoena.

This is well established and copyright holders who have gone after alleged BitTorrent pirates in recent years did so through proper channels. However, late last month the rightsholders of the movie “London Has Fallen” gave it another shot.

In a request at a Utah federal court, it requested the clerk to sign off on a DMCA subpoena identifying 33 alleged BitTorrent pirates on a Comcast connection.

The company in question, LHF Productions, is not unaware of how things are supposed to work. It has sued BitTorrent users through the regular ‘copyright troll’ scheme dozens of times in the past.

This time, however, it opted for the cheaper and easier DMCA subpoena route.

“[T]he Clerk should expeditiously issue and sign the proposed subpoena and return it to the undersigned for delivery to the service provider,” LHF’s attorney Todd Zenger wrote in his request.

Perhaps the company hoped that the demand would slip through or that the court would have other reasons to approve it, but that was not the case. Last week, US District Court Judge David Nuffer denied the request.

The Judge clarified, once again, that Section 512(h) of the DMCA only allows for prelitigation subpoenas when the targeted Internet services actually host or link to the infringing content.

“This provision only applies to ISPs that directly store, cache, or provide links to infringing material. It does not apply to ISPs that merely function as a conduit for infringing material.

“LHF has not identified any material that Comcast should remove or disable, and there is no assertion that Comcast directly stores, caches, or provides links to infringing material,” the Judge writes.
